Description

It replaces the spider gears in the differential, sending power to both rear wheels simultaneously. This mini spool is constructed from high-strength steel for durability.

Ideal for drag racing and off-road applications, this component offers a cost-effective upgrade by eliminating the need for a limited-slip differential. It is designed for a direct fit with factory or aftermarket 31-spline axles.
